You may need custom serialization in java in may cases. For example, you have legacy java classes which you are not willing to modify for any reason. There can be some design constraints as well. Or even simply, the class is expected to be changed in future releases which could break the deserialization of previously […]
RxJava 2.0 is open source extension to java for asynchronous programming by NetFlix. It is much closer to functional programming as seen in java 8 lambda expressions. The basic building blocks of reactive code are Observables and Subscribers. An Observable emits items; a Subscriber consumes those items.
Maven parent POM (or super POM) is used to structure the project to avoid redundancies or duplicate configurations using inheritance between pom files. It helps in easy maintenance in long term. Table of Contents Parent POM Contents Parent POM and Child POM Parent POM Relative Path Parent POM Contents A parent POM can be declared […]
Maven scope attribute is used to specify the visibility of a dependency, relative to the different lifecycle phases (build, test, runtime etc). Maven provides six scopes i.e. compile, provided, runtime, test, system, and import.
Maven repositories are physical directories which contain packaged JAR files along with extra meta data about these jar files. This meta data is in form of POM files which have jar file project information, including what other external dependencies this JAR file has. These other external dependencies are downloaded transitively into your project and become […]
In Maven, dependency is another archive—JAR, ZIP, and so on—which your current project needs in order to compile, build, test, and/or to run. The dependencies are gathered in the pom.xml file, inside of a <dependencies> tag. When you run a build or execute a maven goal, these dependencies are resolved, and are then loaded from […]
POM (Project Object Model) is an XML file that contains information about the project and configuration details used by Maven to build the project i.e. sourcecode location, project dependencies etc. This file must be named as pom.xml and placed under root folder of project.
Maven settings.xml file contains configurations that are not specific to a project, but are global in nature. It also contains information that is not meant to be distributed (e.g. passwords).
JUnit 5 aims to adapt java 8 style of coding and to be more robust and flexible than JUnit 4. In this post, JUnit 5 vs JUnit 4, we will focus on some major differences between them.
Eclipse has great tooling support for JUnit test cases. Having code templates for JUnit test cases configured in Eclipse is a great addition in faster test development. Learn to create and import JUnit 5 test templates in eclipse.
